Mac OS用户在这里。我试图在我的python IDLE中运行一个命令:

from selenium import webdriver
browser = webdriver.Firefox()

我收到以下错误消息:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/selenium/webdriver/common/service.py", line 76, in start
    stdin=PIPE)

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    browser = webdriver.Firefox()

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

我已经brew install geckodriverwhich geckodriver返回/usr/local/bin/geckodriver,所以我确定它已正确安装。好像它似乎还没有正常运行?

您的错误消息非常明确:

FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver'

您必须设置 geckodriver 的路径。有不同的方法可以做到这一点。

您可以在代码中设置geckodriver的路径:

from selenium import webdriver
browser = webdriver.Firefox(executable_path=r'/.../path2Your/geckodriver')

或在 PATH 环境变量中插入geckodriver的路径:

export PATH=$PATH:/.../path2Your/geckodriver

我从未尝试在mac os中的/usr/local/bin/中移动可执行文件。我试过一个ubuntu操作系统,它的工作原理。我认为应该没问题。

可能是因为该文件不可执行。如果不是,请转到/usr/local/bin/并将其设为可执行文件:

chmod +x geckodriver

我正在使用ubuntu 18.04,在这里遇到了同样的问题。

就我而言,这很好。希望对您有用!

sudo apt-get install firefox-geckodriver

答案 2 :(得分:0)

最适合我的事情之一就是复制可执行的geckodriver文件。

进入bin文件夹:

如果您使用的是Linux,则可以在以下位置找到它:

/home/user_name/.local/bin

在此处粘贴您的geckodriver exe。

因此您的最终代码应如下所示:

    from selenium import webdriver
    driver = webdriver.Firefox(executable_path = 'geckodriver')

这对我来说就像魅力一样起作用,但是不确定是否正确。
